[PATCH 3/6] drivers: staging: vme: Fixed the using of sizeof

From: Egor Uleyskiy
Date: Sun Nov 22 2015 - 04:29:01 EST


From: Egor Uleyskiy <egor.ulieiskii@xxxxxxxxx>

Constructions that looks like
card = kzalloc(sizeof(struct pio2_card), GFP_KERNEL);
are changed to
card = kzalloc(sizeof(*card), GFP_KERNEL);
